Minnesota recently enacted a law aimed at restricting misleading AI deepfakes aimed at influencing elections; the law is now being challenged on First Amendment grounds in Kohls v. Ellison. To support the law, the government defendants introduced an expert declaration, written by a scholar of AI and misinformation, who is the Faculty Director of the Stanford Internet Observatory. Here is ¶ 21 of the declaration:
[T]he difficulty in disbelieving deepfakes stems from the sophisticated technology used to create seamless and lifelike reproductions of a person's appearance and voice. One study found that even when individuals are informed about the existence of deepfakes, they may still struggle to distinguish between real and manipulated content. This challenge is exacerbated on social media platforms, where deepfakes can spread rapidly before they are identified and removed (Hwang et al., 2023).
